Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, and thus the present invention is not limited to the specific embodiments disclosed below.
Referring to fig. 1, fig. 1 is a top view of a display panel provided in the present invention. In the research process, the inventor finds that, as shown in fig. 1, when the display panel 100 is pressed, assuming that the pressing force points P are distributed at four corners of the display panel 100, the positions where the stress applied to the display panel is large are peripheral positions shown by dotted lines K1-K5 shown in fig. 1, so that the problem of light leakage due to pressing easily occurs near the peripheral positions of the dotted lines K1-K5 of the display panel, specifically, the light points are finely divided and densely represented. The display panel is usually provided with a special-shaped functional area for placing some functional components, such as a camera or an earphone, and the functional area is generally close to the periphery of the dashed lines K1-K5 shown in fig. 1 or located between two dashed lines, so that the display area near the functional area is more prone to squeeze light leakage. Fig. 1 is a schematic diagram illustrating stress of a display panel when the display panel is pressed, and the present invention is not limited to the case where the display panel is pressed.
Accordingly, the present invention provides a display panel to improve the above problem, fig. 2 is an enlarged sectional view of a partial region G1 along a-a' in a transition region of a display panel provided by the present invention, fig. 3 is an enlarged plan view of a partial region G1 in a transition region of a display panel provided by the present invention, and as shown in fig. 1, 2 and 3, a display panel 100 includes a display region AA, a non-display region FA surrounding the display region AA, and a functional region N, the display region AA surrounding at least a part of the functional region N; the display area AA includes a transition area G and a non-transition area FG, and the transition area G is located between the non-transition area FG and the functional area N.
Optionally, the display area AA includes a first edge E1 and a second edge E2, the first edge E1 further includes a shaped edge ES, the remaining portion of the first edge E1 except the shaped edge ES extends along the first direction X, the second edge E2 extends along the second direction Y, and the shaped edge ES is recessed toward the inside of the display area AA to form the functional area N. The shaped edge ES shown in fig. 1 is formed by connecting three straight edges, and here, the shape of the shaped edge is not limited to that shown in fig. 1, and the shaped edge may be an arc-shaped edge, etc. A part of the functional region N is adjacent to the transition region G, and the non-transition region FG surrounds the part of the transition region G. Here, the surrounding includes both the half surrounding and the full surrounding, as shown in fig. 1, the non-transition region FG half surrounds the transition region G, the display region AA half surrounds the functional region N, the non-display region FA full surrounds the display region AA, and the non-transition region FG is not adjacent to the functional region N.
As shown in fig. 2, the display panel 100 includes an array substrate 20 and a color filter substrate 10 that are disposed opposite to each other, a black matrix 11 and a plurality of spacers 13 are disposed on a side of the color filter substrate 10 facing the array substrate 20, the color filter substrate 10 further includes a red color resistor r, a green color resistor g, a blue color resistor b and a planarization layer 12, and an orthogonal projection of the spacers 13 on the color filter substrate 10 is located in an orthogonal projection of the black matrix 11 on the color filter substrate 10, where a collocation manner of the color resistors shown in fig. 2 is only schematic, and the color resistors may also be a collocation manner of the red color resistor, the green color resistor, the blue color resistor and the white color resistor, so a collocation manner of the color resistors is not specifically limited; the structural design of the array substrate is not particularly limited in the present application; the figures in the application are only schematic and are not specifically limited as to the position relationship between the spacer and the color resistor; the number of spacers shown in the drawings of the present application is also illustrative and not particularly limited.
It should be noted that the black matrix mentioned in the present application has a good light shielding effect, and is not described herein again.
As shown in fig. 3, the spacer 13 disposed in the region of the transition region G corresponding to the color filter substrate 10 is a first spacer 131. Along the preset direction YS, the first length L corresponding to the first spacer 131 gradually decreases. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, and the preset direction YS is a direction from the non-transition region FG to the transition region G.
Since, in the embodiment shown in fig. 1, the transition region G surrounds part of the functional region N, and the non-transition region FG surrounds part of the transition region G, there are a plurality of preset directions YS, and the design manner of the spacers in the preset directions in other directions will be described as an example.
Fig. 4 is an enlarged plan view of a local region G2 in a transition region of a display panel provided by the present invention, and referring to fig. 1 and fig. 4, the spacer disposed in the region of the color film substrate 10 corresponding to the transition region G is the first spacer 131. Along the preset direction YS, the first length L corresponding to the first spacer 131 gradually decreases. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, and the preset direction YS is a direction from the non-transition region FG to the transition region G.
Fig. 3 and 4 are only examples of the case where the preset direction YS is parallel to the second direction Y and the first direction X, respectively, and a detailed description thereof is omitted here.
The positions of the spacers shown in fig. 3 and fig. 4 are only schematic, and the spacers may be adjacent to any two of the red color resistor r, the green color resistor g, and the blue color resistor b.
Alternatively, as shown in fig. 3 and 4, the minimum distances S from the geometric centers of the orthographic projections of all the spacers 13 on the black matrix 11 to the edges of the black matrix in the display panel 100 are the same. I.e., the positional relationship of all spacers within the display panel with respect to the color resists and the black matrix edges, is consistent, although the same here means substantially the same, not absolutely the same, within the conventional process fluctuation range.
Alternatively, as shown in fig. 3 and 4, the first distance H gradually increases along the preset direction YS, and the first distance H is a minimum distance between an edge of the orthographic projection of the first spacer 131 on the black matrix 11 and an edge of the black matrix 11.
Optionally, let T denote the pressing force applied to the display panel, and S ', S' and T satisfy the following empirical formula:
S′＝tT+0.58
here, S' is in μm, T is in Newton (N), T is in μm/N, and T is a proportionality coefficient, and since this formula is an empirical formula, T has a value in the range of 2.5 to 3.0, and may be 2.7.
It should be noted that the minimum distance S from the geometric center of the orthographic projection of all the spacers 13 in the display panel 100 on the black matrix 11 to the edge of the black matrix needs to be satisfied, where S is smaller than or equal to S'. The empirical formula provided by the present embodiment is advantageous for finding a suitable S value.
When the display panel is pressed or extruded, the pressed or extruded part, the position extending along the stress direction and the area nearby the position are relatively large in force, so that the spacer at the position with the large force is easy to incline, the array substrate or the color film substrate corresponding to the inclined position can generate film layer damage, and the film layer damage can cause light leakage, namely, the extrusion light leakage phenomenon of the spacer can be expressed as fine and dense bright spots.
Since the display panel provided by the invention is provided with the functional area, the functional area of the display panel has no display function, and the display panel of the functional area is designed to be hollowed out, and the process implementation manner of the hollowed-out design can be various, and is not specifically limited and described herein. Because the existence of functional area for the non-display area of display panel is the dysmorphism in frame district, so, when display panel received the extrusion or pressed, the stress atress of the display area adjacent with the functional area among the display panel can be bigger, then the shock insulator of the display area adjacent with the functional area inclines more easily, so the display area near the functional area of display panel is changeed and is produced the extrusion light leak phenomenon.
In view of this, in the display panel provided in this embodiment, the transition region is disposed in the display region close to the functional region, a length of an orthographic projection of the spacer disposed in the transition region on the color film substrate along the preset direction, that is, the first length L, is gradually decreased, and a minimum distance S from a geometric center of an orthographic projection of all spacers in the display panel on the black matrix to an edge of the black matrix is kept consistent, so that a minimum distance H from an edge of the orthographic projection of the spacer in the transition region on the black matrix to an edge of the black matrix in the preset direction is gradually increased. That is, the distance between the spacer closer to the functional region and the edge of the black matrix is larger, and the black matrix has a light shielding effect, so that light leakage generated when the spacer is inclined can be effectively shielded when the display panel is stressed, and thus, the phenomenon of extrusion light leakage generated around the special-shaped functional region of the display panel due to stress influence can be improved.
Optionally, fig. 5 is a top view of another display panel provided by the present invention, as shown in fig. 5, the display panel 100 includes a display area AA, a non-display area FA, and a functional area N, the non-display area FA surrounds the display area AA, the display area AA surrounds a part of the functional area N, the display area AA includes a transition area G and a non-transition area FG, the part of the functional area N is adjacent to the transition area G, and the part of the functional area N is adjacent to the non-transition area FG. The non-transition region FG surrounds the transition region G halfway, and is adjacent to both the transition region G and the functional region N. The display area AA includes a first edge E1 and a second edge E2, the first edge E1 further includes a shaped edge ES, the rest of the first edge E1 except the shaped edge ES extends in the first direction X, the second edge E2 extends in the second direction Y, and the shaped edge ES is recessed inside the display area AA to form a functional area N.
In contrast to fig. 1, the position of the transition region G in fig. 5 is another case where the transition region G is located between the non-transition region FG and the functional region N, so the present invention does not specifically limit the shape of the transition region as long as the transition region is satisfied between the non-transition region and the functional region.
Similarly, the enlarged plan view of the partial region G1 in fig. 5 is the same as that shown in fig. 3, and with reference to fig. 5 and 3, the spacer disposed in the region of the color filter substrate corresponding to the transition region G is the first spacer 131. Along the preset direction YS, the first length L corresponding to the first spacer 131 gradually decreases. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, and the preset direction YS is a direction from the non-transition region FG to the transition region G, obviously, the preset direction in this embodiment is only one direction, such as the preset direction YS shown in fig. 4.
In the display panel provided by the embodiment, the transition region and the functional region are partially adjacent to each other, and there is only one preset direction in the design, so that the trend change of the gradual decrease of the first length L corresponding to the first spacer 131 in the display panel is only along one direction, the design is simple, and the process is relatively simple and easy to implement.
Alternatively, fig. 6 is a top view of another display panel provided by the present invention, and a magnified plan view of a partial area G1 in fig. 6 is the same as that shown in fig. 3, and in conjunction with fig. 6 and fig. 3, the display panel 100 includes a display area AA, a non-display area FA surrounding the display area AA, and a functional area N surrounding the entire functional area N, where the functional area N is a closed figure, the display area AA includes a transition area G and a non-transition area FG, the transition area G is located between the non-transition area FG and the functional area N, the transition area G surrounds the entire functional area N, and the non-transition area FG surrounds the entire transition area G.
In this embodiment, a through hole penetrating through the display panel is formed in a direction perpendicular to the display panel, a camera, a flash lamp or other functional components are placed in the through hole, and a planar pattern formed by the through hole on the display surface of the display panel is the functional region N. The transition region G is located between the non-transition region FG and the functional region N, the transition region G surrounding the entire functional region N, the non-transition region FG surrounding the entire transition region G. The shape of the functional region N shown in fig. 6 is merely illustrative, and may be a polygon, a circle, an ellipse, or the like, and the shape of the functional region N is not particularly limited in the present invention.
As shown in fig. 3, the spacer disposed in the region of the color filter substrate 10 corresponding to the transition region G is a first spacer 131. Along the preset direction YS, the first length L corresponding to the first spacer 131 gradually decreases. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, the preset direction YS is a direction from the non-transition region FG to the transition region G, since the functional region of the embodiment is a closed figure, a plurality of preset directions exist, the preset directions shown in fig. 6 are only schematic, the embodiment is not limited by a mark in the figure, and any direction from the non-transition region to the transition region is a preset direction.
The display panel that this embodiment provided establishes the through-hole that runs through display panel through in the direction of perpendicular to display panel, and the plane figure that the through-hole formed on display panel's display surface is the functional area promptly, then the functional area is closed figure, and this kind of design can be according to the appearance settlement of customer's demand random switching functional area, can solve easily to produce the problem of extrusion light leak around the functional area, makes display panel's functional area appearance changeable again.
Optionally, fig. 7 is a plan enlarged view of a local region G1 in a transition area of a display panel provided by the present invention, fig. 8 is a plan enlarged view of a local region G1 in a transition area of another display panel provided by the present invention, and with reference to fig. 1, fig. 2, fig. 3, fig. 7 and fig. 8, a shape of an orthographic projection of the spacer 13 on the color filter substrate shown in fig. 3 is an ellipse, a shape of an orthographic projection of the spacer 13 on the color filter substrate shown in fig. 7 is a diamond, a shape of an orthographic projection of the spacer 13 on the color filter substrate shown in fig. 8 is a hexagon, here, a shape of an orthographic projection of the spacer on the color filter substrate may be any one or any two of a circle, an ellipse and a polygon, and the shape of an orthographic projection of the spacer on the color filter substrate is not limited as long as the shapes belonging to a circle, an ellipse and a polygon are within the protection scope of the present application, the specific shape may be determined as appropriate.
No matter what the shape of the orthographic projection of the spacer on the color film substrate is, the requirement is met, and along the preset direction YS, the first length L corresponding to the first spacer 131 is gradually reduced. The spacer arranged in the region of the color film substrate 10 corresponding to the transition region G is a first spacer 131. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, and the preset direction YS is a direction from the non-transition region FG to the transition region G.
The display panel provided by the embodiment has diversified shape designs of orthographic projections of the spacers on the color film substrate, can be adjusted according to specific design requirements, and is high in flexibility in the panel design process.
Alternatively, fig. 9 is a plan enlarged view of a partial region G1 in a transition region of another display panel provided by the present invention, and as shown in fig. 9, sub-pixels in the display panel are respectively represented by a red color resistance r, a green color resistance G, and a blue color resistance b, and all the sub-pixels in the display panel respectively extend along two different intersecting directions, which is generally referred to as a dual chip design. The double chip design shown in fig. 9 is referred to as a fake double chip in the display technology field, and further details of the true double chip design are not repeated here, and fig. 9 is only schematic for the double chip design, and the arrangement design of the pixels is not specifically limited in the present invention.
Optionally, fig. 10 is a plan enlarged view of a local region G1 in a transition region of another display panel provided by the present invention, and as shown in fig. 10, the spacer arranged in the region of the color film substrate 10 corresponding to the transition region G is a first spacer 131. Along the preset direction YS, the first length L corresponding to the first spacer 131 gradually decreases. The first length L is a length of an orthographic projection of the first spacer 131 on the color film substrate 10 along a preset direction YS, and the preset direction YS is a direction from the non-transition region FG to the transition region G; along the preset direction YS, a second length W corresponding to the first spacer 131 gradually increases, and the second length W is a length of an orthographic projection of the first spacer 131 on the color film substrate along a direction perpendicular to the preset direction YS.
Specifically, with continued reference to fig. 10, the minimum distances S from the geometric centers of the orthographic projections of all the spacers 13 on the black matrix 11 to the edges of the black matrix within the display panel 100 are the same. I.e., the positional relationship of all spacers within the display panel with respect to the color resists and the black matrix edges, is consistent, although the same here means substantially the same, not absolutely the same, within the conventional process fluctuation range. By setting the first length L corresponding to the first spacer 131 to be gradually decreased and the second length W corresponding to the first spacer 131 to be gradually increased along the preset direction YS, it is further possible to gradually increase the first distance H along the preset direction YS, where the first distance H is a minimum distance between an edge of the orthographic projection of the first spacer 131 on the black matrix 11 and an edge of the black matrix 11.
In the display panel provided by this embodiment, the first length L corresponding to the first spacer 131 is gradually decreased and the second length W corresponding to the first spacer 131 is gradually increased in the preset direction, so that the minimum distance from the edge of the orthographic projection of the spacer in the transition region on the black matrix to the edge of the black matrix is more obviously gradually increased in the preset direction. Therefore, when the minimum distance from the orthographic projection edge of the spacer in the transition area to the edge of the black matrix is gradually increased, namely the distance from the spacer in the transition area closer to the functional area to the edge of the black matrix is larger, the black matrix has a light shielding effect, when the display panel is stressed, light leakage generated when the spacer is inclined can be effectively shielded, and therefore the extrusion light leakage phenomenon generated at the periphery of the special-shaped functional area of the display panel due to stress influence can be improved.
Optionally, with reference to fig. 10, the first length L corresponding to the first spacers 131 is gradually decreased, and the second length W corresponding to the first spacers 131 is gradually increased along the preset direction YS, on this basis, the orthographic projection areas of the first spacers 131 on the color filter substrate are equal. It is obvious that the equality here is not an absolute equality, but an equality within the scope of the production process accuracy fluctuations, where equality requires reference to process accuracy error values and is not absolutely limited here.
The display panel provided by this embodiment sets the orthogonal projection areas of all the first spacers in the transition region on the color film substrate to be equal, so that the manufacturing process is simple and easy to implement,
optionally, fig. 11 is a cross-sectional enlarged view along B-B of a local region FG1 in a non-transition area of a display panel provided by the present invention, and fig. 12 is a plan enlarged view of a local region FG1 in a non-transition area of a display panel provided by the present invention, as shown in fig. 1, fig. 11 and fig. 12, where the spacer 13 is in a column shape, one end of the spacer 13 close to the array substrate 20 is a first end 13T, an orthogonal projection of the first end 13T of the spacer 13 on the color filter substrate 10 is a first projection 13TY, one end of the spacer 13 close to the color filter substrate 10 is a second end 13C, an orthogonal projection of the second end 13C of the spacer 13 on the color filter substrate 10 is a second projection 13CY, and the first projection 13TY falls within the second projection 13 CY.
With reference to fig. 11 and 12, the spacer 13 disposed in the non-transition region FG corresponding to the color filter substrate 10 is a second spacer 132, and in a unit area of the display panel, a sum of areas of first projections of the first spacer on the color filter substrate is equal to a sum of areas of first projections of the second spacer on the color filter substrate.
In the display panel provided by this embodiment, by setting that the sum of the areas of the first projections of the first spacers on the color film substrate in a unit area is equal to the sum of the areas of the first projections of the second spacers on the color film substrate, the supporting effect of the spacers in the transition area of the display panel on the array substrate and the color film substrate can be the same as the supporting effect of the spacers in the non-transition area of the display panel on the array substrate and the color film substrate, and therefore, the supporting effect of the spacers in all the display areas of the display panel can be uniform, so that the display of the display panel is uniform, and the display effect is better.
Optionally, fig. 13 is a cross-sectional enlarged view of a local area FG1 in a non-transition area of another display panel provided by the present invention along B-B, as shown in fig. 13, a plurality of auxiliary supporting pillars 14 are disposed on a side of the color filter substrate 10 facing the array substrate 20, an orthogonal projection of the auxiliary supporting pillars 14 on the color filter substrate 10 is located in an orthogonal projection of the black matrix 11 on the color filter substrate 10, and a height Z of the auxiliary supporting pillars 14 is smaller than a height Z of the spacer 13 in a direction perpendicular to a display surface of the display panel.
It should be noted that the auxiliary supporting in fig. 13 is only schematically shown, and the number relationship between the auxiliary supporting columns and the spacers is not specifically limited in this embodiment, and the positions of the auxiliary supporting columns relative to the color resists and the black matrix are also not specifically limited.
The display panel that this embodiment provided sets up auxiliary stay post and can plays auxiliary stay's effect, and when display panel received external force extrusion, when the shock insulator atress warp to a certain extent, the auxiliary stay post can play corresponding supporting role, can effectively strengthen display panel's intensity.
Due to the influence of stress, when the display panel or the display device is pressed or squeezed, a squeezing light leakage phenomenon is very easily generated around the special-shaped functional area of the display panel, and the phenomenon is particularly expressed as fine and dense bright spots. According to the display panel provided by the invention, the length of the orthographic projection of the spacer on the color film substrate, which is close to the display area of the functional area, along the preset direction is gradually reduced, so that the extrusion light leakage phenomenon generated around the special-shaped functional area of the display panel due to the influence of stress can be improved.
Fig. 14 is a top view of a display device according to the present invention, and as shown in fig. 14, the display device includes any one of the display panels provided in the above embodiments. The display device in fig. 14 is only schematic and does not show the functional region, and the shape and position of the functional region are not particularly limited in this embodiment. The display device can be an electronic device with a display function, such as a mobile phone, a tablet computer, a notebook computer, a display and the like, has the relevant characteristics and the corresponding technical effects of the display panel, and is not repeated herein.
The invention has the following beneficial effects: when the display panel is pressed or extruded, the pressed or extruded part, the position extending along the stress direction and the area nearby the position are relatively large in force, so that the spacer at the position with the large force is easy to incline, the inclined position can cause corresponding film damage, and the film damage can cause light leakage, namely, the extrusion light leakage phenomenon of the spacer can be expressed as fine and dense bright spots.
Still further, since the display panel provided by the present invention is provided with the functional region, the functional region of the display panel does not have a display function, and the display panel of the functional region is designed to be hollowed out, and the process implementation manner of the hollowed-out design may be various, which is not specifically limited and described herein. Because the existence of functional area for display panel's non-display area is the frame district and is special-shaped, so, when display panel received the extrusion or pressed, display panel and the stress atress of the adjacent display area of functional area can be bigger, then the spacer of the adjacent display area of functional area inclines relatively easily, the position after the slope can cause corresponding rete damage, the rete damage can cause the light leak, so the display area near display panel's the functional area is changeed and is produced the extrusion light leak phenomenon.
In view of this, in the display panel provided in this embodiment, the transition region is disposed in the display region close to the functional region, the length of the orthographic projection of the spacer disposed in the transition region on the color film substrate along the preset direction is gradually decreased, and the minimum distances from the geometric centers of the orthographic projections of all the spacers in the display panel on the black matrix to the edge of the black matrix are kept consistent, so that the minimum distance from the edge of the orthographic projection of the spacer in the transition region on the black matrix to the edge of the black matrix is gradually increased in the preset direction. That is, the distance between the spacer closer to the functional region and the edge of the black matrix is larger, and the black matrix has a light shielding effect, so that light leakage generated when the spacer is inclined can be effectively shielded when the display panel is stressed, and thus, the phenomenon of extrusion light leakage generated around the special-shaped functional region of the display panel due to stress influence can be improved.
